From c2cf0ecab5455f41ab56c131b21e153a3befa8b0 Mon Sep 17 00:00:00 2001 From: Lukas Straub Date: Sun, 18 Jul 2021 16:48:42 +0200 Subject: [PATCH] replication: Remove workaround Remove the workaround introduced in commit 6ecbc6c52672db5c13805735ca02784879ce8285 "replication: Avoid blk_make_empty() on read-only child". It is not needed anymore since s->hidden_disk is guaranteed to be writable when secondary_do_checkpoint() runs. Because replication_start(), _do_checkpoint() and _stop() are only called by COLO migration code and COLO-migration activates all disks via bdrv_invalidate_cache_all() before it calls these functions.
